Document Summary
Key concepts: darwin"s ideas challenged traditional views, descent with modification explains both the unity and diversity of life, evolution is supported by scientific evidence. Aristotle proposed the scala naturae (scale of nature) in which each from of life has an allotted rung on the ladder. Carolus linnaeus was a 1700s swedish physician who sought to classify life"s diversity for the glory of god. He developed a 2-part format for naming species. Adopted a nested classification system, which grouped similar species into categories. Darwin later argued that classification should be based on evolutionary kinship. Fossils remains or traces of organisms from the past. Strata superimposed layers of rock made of sediment, in which fossils are found. Paleontology study of fossils, developed by georges cuvier. Jean baptiste de lamarck proposed use and disuse idea that parts of the body that are used extensively become larger and stronger. Proposed the idea that organisms could pass modifications to offspring.
